Abstract
Disclosed herein is a radiation image information reader equipped with two line detection sections. The photostimulated luminescent light emitted by irradiation of excitation light is detected by the two line detection sections. Also, the photostimulated luminescent light emitted from an excitation-light irradiated portion corresponding to adjacent portions in a plurality of line sensors of one of the two line detection sections, is detected by the other line detection section in which adjacent portions are disposed at positions shifted predetermined distances from the adjacent portions of the one line detection section.
Claims23
A radiation image information reader comprising
- irradiation means for irradiating excitation light in line form to a portion of a top surface of a storable phosphor sheet storing radiation image information therein;
- detection means having a line detection section in which a large number of photoelectric conversion elements for detecting photostimulated luminescent light, emitted from the excitation-light irradiated line portion or a portion of a bottom surface of aid sheet corresponding to said excitation-light irradiated line portion, are arrayed parallel to said excitation-light irradiated line portion;
- scan means fore relatively moving one of (1) said irradiation means and detection means and (2) said phosphor sheet with respect to the other in a direction different from a length direction of said irradiated line portion;
- and
- read means for reading an output of said detection means sequentially according to said movement and then obtaining data which constituted a final image;
- wherein the line detection section of said detection means is constituted by a plurality of line detection sections wherein said line detection section includes a plurality of line sensors arrayed adjacent to one another in a direction parallel to said irradiated line portion;
- wherein said photostimulated luminescent light emitted from the irradiated line portion is detected by said plurality of line detection sections;
- and
- wherein said line sensors are arrayed so that adjacent portions in said line sensors are disposed at positions shifted predetermined distances from said adjacent portions.
